MATI Spectroscopical Detection Of Geometry Changes Of Aromatic Molecules In The Ionic State

Since its introduction the MATI (mass analyzed threshold ionization) spectroscopy has been an important technique for the investigation of molecular ions with lasers. The energies of molecular states and in particular the ionization energy can be determined with very high accuracy. A major problem of MATI spectroscopy is the reduced signal strength compared for example with ZEKE (zero kinetic energy) spectroscopy which analyzes electrons instead of ions. MATI spectroscopy was applied in the investigation of pyridine and the three isomers of environmentally toxic di-chloro-benzene. Thus new resonances of these cations could be found and geometry changes could be identified by observation of the violation of the '{delta}{nu} 0-propensity rule'.
